1. Hong Kong Population
Areas with higher populations tend to experience a more pronounced UHI effect due to increased heat generation and retention associated with human activities and urban infrastructure. As such, we collect 2011/2016/2021 demographic data from Hong Kong Common Spatial Data Infrastructure Portal to see the distribution and trend of population. Specifically, we look into total population and average age in the exploratory analysis.

As seen in the map, the population is primarily concentrated in the central urban districts, which include Kwun Tong District, Yau Tsim Mong District, Kowloon City District, Wong Tai Sin District, Sham Shui Po District, and Eastern District across Victoria Harbour. The population density diminishes as the distance from the center increases.
We have developed an interactive dashboard that provides demographic data for the years 2011, 2016, and 2021, organized by District Council District. This dashboard offers a detailed breakdown of densely populated areas, with a particular focus on the central urban district. Interestingly, we can also identify numerous smaller districts with significant population clusters in the outskirts of Hong Kong. For average age distribution especially in recent years, they are more likely to cluster in the core areas, followed by the New Territories in the north.
